Because the human heart requires only a small amount of electrical stimulation, researchers were able to shrink their next-generation pacemaker even smaller. The final result is a 1-millimeter ...

Specialized cells in your heart’s right atrium called the sinus node (sinoatrial, or SA, node) usually control its rhythm. The SA node acts as a natural pacemaker, creating the electrical ...
